Specification of Letters Patent.

Patented J line 23, 1914.

Application filed February 28, 1913. Serial No. 751,275.

To a?! whom it may concern Allegheny and State of Pennsylvania, acitizen of the lnited States. have invented or discovered certain newand useful Improvements in Packing-Boxes, of which improvements thefollowing is a specification.

My invention has to do with collapsible packing boxes adapted to containarticles for delivery, shipment by express or parcel post. etc.

The object of my invention is to provide a box of the characterdescribed, wherein all the parts of the box form a unitary blank whencollapsed. such box being firm and rigid in construction. and easy tomanipulate.

More specifically stated, the object of my invention. as far as themanipulation of such boxes is concerned. is to provide a box a which maybe easily brought from flattened blank position to box-form and lockedinto such form, the lid thereof being free to open and close. and whichbox may be subsequently effectively locked.

in the accompanying drawing, which forms part of mv specification. lhave illustrated one embodiment. of my invention.

Figure 1 is a view of the blank: Fig. 2 is a perspective view of the boxpartly closed. illustrating the manner of cfi'ccting such closing: Fig.l is a perspective view of the box when brought to and locked into boxform. the lid being free to open and close; and Fig. 4 is a perspectiveview of the box with the lid locked in closed position.

Tn the several figures like numerals are used to designate like parts.

The box shown herein is made from cor-- rugated cardboard. which. it iswell known. bends easily along a line formed by scoring the surfacethereof. However it will be readily understood that any other blankmaterial suitable for the intended purpose may dependently formed ofsuitable stiff material and joined together into a hinged unitary blank.

The blank of corrugated cardboard. when forming the illustrativeembodiment of my invention. is out and scored as indicated in Fig. 1.the full lines between adjacent box parts indicating cuts in the blank.and the dotted lines indicating the scored portions i i l 3. lid 4 andlid-flap I the parts 1, 2, 3 and 4 there are flaps 6', 7, 8,

. of the board forming hin es between such Be it known that l. FnnnnnicnA. Dnoz, "esiding at Fair Oaks. in the county ofparts. The front side oft e box is formed from the end of the blank, and is indicated in thedrawings by the numeral 1. The parts of the box, as they aresuccessively arranged from said side are bottom 2, rear side At one endof each of and 9. respectively, and at the opposite ends of said partsthere are flaps 6-, 75, 8 and 9", respectively. the tla s 7 and 7*forming the cm s of the box an the other flaps forming reinforcingsections.

In order to facilitate the folding and further manipulation of the box Iprovide a single means for bringing the blank from its flattenedposition to box form and for locking it in such form, the lid bein freeto move. such means also being e ective to lock said lid in closedposition. The preferred means which I employ to such an end is aflexible wire. tape or cord 10, which, in this embodiment of myinvention is tightly attached to eyelets l1 and 12 in the side 1 andflap (3. respectively. and extends loosely through eyelets i3. 14, 14*.13, 12 and 11 in the several members, as clearly shown in the drawing.

it will readily be seen that the box in flattened form may be brought tobox-form by pulling the loose or unsecured end of the cord 10. theposition of the box when partly folded being shown in Fig. 2; and inthus effecting a closing of the box there is no binding of the cord orcrushing of the box portions. When the cord has been pulled taut. thebox is in the form illustrated in Fig. 3. the lid 4 being free to openand close as desired. The desirability of locking or securing the box inthe position shown in Fig. 3 is clearly apparent. and to such an end Iarrange the cord 10 outside of the end 7 so that the loose end of thecord may be drawn between said end and the taut portion of the cordextending over its exterior face.

he used. or the parts of the box may be inlt will be understood thatthus binding the loose end of the cord will accomplish an effectivelocking of the body portion of the 1 box in closed position: however. inorder to i obtain a more secure looking. a knot 15 may be formed asshown in Fig. 4. When in this position the box may be handled whilearticles are being placed therein without the liability of itscollapsing.

In the final securing of the box I efi'ect a double locking of the lid,so that, in case the cord is broken or cut at one point, another part ofthe cord will keep the lid in closed position. The first locking isaccomplished by forming a knot 15 at the eyelets 11 and 12*, as shown inFig. 4, so that the beveled flaps 9, 9 may, while the lid is beingclosed,

' be slipped between the ends 7 and 7 respecof construction shown antively, and the cord on their outer surfaces, the flaps thereby addingtension to or tightening the cord, which in turn holds the flaps, andthrough such lugs, the lid in closed position. The second locking of thelid is preferably effected by placing the lid fiap 5 over the outersurface of the front side 1 and in tying the loose ends of the cord 10,as shown in Fig. 4. To the end that the cord may more effectively holdthe flap 5 in closed position notches 16 and 16" are formed in the flap,such notches being, when the lid is closed, adjacent to the eyelets 11and 11, respectively. It will be seen that the cord is thus, in effect,divided into two portions each of which may hold the lid in closedposition in case the other portion is broken. One of said cord portionsis the part extending from the eyelets 11 and 12 around the back of thebox to the eyelets l1 and 12, and, as stated above, this-portion of thecord engages the flaps 9 and 9 of the lid 4. The other of said cordportions extends from e elets 11 and 12 to e elets 11 and 12 over t efront side of the ox and engages the lid fla 5.

I do not wish to limit m sel to the details (l described herein, or tothe particular form of box I have illustrated, for obviously manychanges may be made by those skilled in the art without (leparting fromthe spirit of my invention as defined in the following claims.

I claim as my invention:

1. A folding box having a bottom portion, front and rear sides, ends,and lid formed of a single blank, said lid extending from the to of therear side and provided with a flap a apted to extend over said frontside, a single cord secured near an end thereof to the front side ofsaid box and having sliding engagement with the rear side thereof andwith said front side, said cord extending over said fla when the lid isclosed thereby holding the lid in closed position.

2. A folding box having a bottom portion, front and rear sides, ends andlid formed of a single blank. said lid extendin from the top of saidrear side and provided with a flap adapted to extend over said frontside, there beln wedging flaps extending from each end 0 said lid, saidends extending one from each end of said bottom portion, and a singlecord secured near an end thereof to the front side of said box andhaving sliding engagement with the rear side thereof and with said frontside, the wedging flaps at the ends of the lid being adapted when thelid is closed to extend between said end portions and the cord on theoutside thereof, thereby tightening the cord.

In testimony whereof I have hereunto set my hand.
